Part - 46 CCNA Interview Questions and Answers

241 A ISDN PRI circuit can be described as which of the following?

A.) 24 B channels and 1-64Kbps D channel

B.) 23 B channels and 1-64Kbps D channel

C.) 2-D channels and 1-C channel

D.) 2-64Kbps B channels and 1-16Kbps D channel

Ans B

There are two types of ISDN Channels: BRI (Basic Rate Interface) - is 2 64Kbps B channels for data and one 16Kbps D channel for link management. PRI (Primary Rate Interface) - is 23Kbps B channels and 1 64Kbps D channel.

242 What are 3 ways to provide login access to router?

A.) Console

B.) TFTP

C.) Rlogin

D.) Auxiliary Port

E.) X Windows

F.) Telnet

Ans A D F

The three ways to provide login access to the router are via the Console port, auxiliary port, and virtual terminal (Telnet)

243 Which of the following statements are true?

A.) Store and forward switching creates variable latency through the switch

B.) Cut through switching creates variables latency through the switch

C.) Cut through switching works at wire speed

D.) Store and forward switching works at wire speed

Ans A C

The larger the packet, the greater the latency when using a switch with Store and Forward methods. This is due to the fact that Store and Forward switching copies the entire Frame into its buffer before forwarding the frame. Cut Through switching only examines the destination address before forwarding the packet and does not copy the frame into its buffer.

244 Which of the following can reply to a Novell Get Nearest Server (GNS) request?

A.) Local Novell server

B.) Remote Novell Printer

C.) Cisco router

D.) Novell client

Ans A C

Cisco routers can act like Novell servers to an extent. They can answer Get Nearest Server request by clients. Of course, both Local and Remote Novell servers can reply to the GNS request. As with Novell servers, Cisco routers can be configured to either reply, or not reply to GNS request by clients. Since each Novell server and Cisco router builds a dynamic table of resources, they can reply to a clients request for the available resources closest to them.

245 Identify the 3 kinds of routes IGRP advertises?

A.) Interior

B.) Dynamic

C.) System

D.) Exterior

Ans A C D

IGRP is a distance vector routing protocol designed by Cisco. The maximum hop count is 255, and it uses a combination of variables to determine a composite metric. IGRP has an administrative distance of 100. There are three types of routes IGRP advertises:
1) Interior,
2) Exterior, and
3) System.

246 What is the routing metric used by RIP?

A.) Route poisoning

B.) Split horizon

C.) Hop Count

D.) TTL

Ans C

Routing Information Protocol (RIP) is a distance vector routing protocol that used hop count as its metric. The maximum hop count is 15, 16 hops is considered unreachable. RIP updates are broadcast every 30 seconds by default. RIP has an administrative distance of 120.

247 What is the default encapsulation and frame type on an Ethernet interface when enabling Novell?

A.) SNAP

B.) Ethernet_II

C.) 802.2

D.) 802.3

E.) SAP

F.) Token_SNAP

Ans D

By default, when an encapsulation type is not specified, the 802.3 frame type is used.

248 What is true when creating static route?

A.) The mask parameter is optional

B.) The administrative distance is required

C.) The gateway parameter is required

D.) The administrative distance is optional

Ans C D

When creating a static route, the gateway parameter is required, but the administrative distance is optional. The correct syntax is: Router(config)# ip route
